Biography
Dr. Hooshang Heshmat is Lead-Founder and President/CEO & Technical Director of Mohawk Innovative Technology, Inc. (MiTi), an internationally renowned applied research and product development company dedicated to green technology. His company specializes in the design, integration and development of mechanical components such as advanced oil-free foil bearings, seals, and dampers, including powder, solid film coatings and dry and fluid film bearings into high-speed oil-free rotating machinery systems. Developed rotating machines employing his novel tribological devices include oil-free compressors, high-speed motors and generators, and gas turbine engines down to Mesoscopic sizes. He has developed special tribological testing methods and measurement techniques and has designed and fabricated the corresponding component test equipment. Dr. Heshmat has established MiTiHeart® one of the premier biotechnology companies in the Albany area based on their unique heart pump system, which uses magnetic levitation.
An STLE and ASME Fellow since 1998, he is listed in Who’s Who in the World, Who’s Who in America and has received numerous STLE and ASME awards: STLE 1983 Wilbur Deutsch Memorial Award, ASME 1985 Burt L. Newkirk Award, STLE 1993 Captain Alfred E. Hunt Award, ASME/RCT 1995 Creative Research Award, STLE 1996 Al Sonntag Award, ASME/IGTI 1999 Best Paper Award, ASME 2002 Thomas A. Edison Patent Award, STLE 2003 Frank P. Bussick Award, ASME IGTI 2005 Microturbine and Small Turbomachinery Committee Best Paper Award, the ASME 2007 Mayo D. Hersey Award, the STLE 2008 International Award, the Pennsylvania State University 2009 Alumni Achievement Award and the ASME 2009 Propulsion Best Paper Award.
Dr. Heshmat received his BSME from Pennsylvania State University and his MSME and Ph.D. in Mechanical Engineering from RPI. He is the leading authority in foil bearings and powder lubrication technologies. He has played a primary role in the development of compliant foil bearings & seals and has been responsible for major advances in this field, including analytical and experimental research for bearing & seal design and application. Dr. Heshmat holds 28 patents, has authored/co-authored more than 175 papers, and has co-authored 2 chapters (Principles of Bearing Design for the Compressor Handbook and Principles of Gas Turbine Bearing Lubrication and Design for the Theory of Hydrodynamic Lubrication).
